The sensors make use of microfluidic technologyâ##developed by Abraham Stroock associate professor of chemical and biomolecular engineeringâ##that places a tiny cavity inside the chip.
and then the chip may be inserted in a plant stem or in the soil where it through a nanoporous membrane exchanges moisture with its environment and maintains an equilibrium pressure that the chip measures.

#First realization of an electric circuit with a magnetic insulator using spin waves Abstract: Researchers at the University of Groningen, Utrecht University, the Universit de Bretagne Occidentale and the FOM Foundation have found that it is possible to make an electric circuit with a magnetic insulator.
This was deemed first impossible. The circuit is realized using spin waves: wavelike perturbations in the magnetic properties of a material.
Their discovery is interesting for the development of novel, energy-efficient electronic devices, particularly integrated circuits. A device based on spin waves could theoretically operate more efficiently than ordinary electronic circuits.
The results of their research will be published online in Nature Physics on Monday 14 september. In our current electronic equipment, information is transported via the motion of electrons.
Duine from Utrecht University have succeeded to use spin waves in an electric circuit by carefully designing the device geometry.
and hence enables the spin waves to be used in an electric circuit. The spin wave circuit that the researchers built,

#Computer Chips Can Now Be made From Wood Not quite what we had in mindthe woods are lovely, dark, deep,
researchers announced the construction of computer chips made from wood. But don't expect to see hipsters advertising hand-carved artisan computer chips.
The wood product that the scientists are using is called cellulose nanofibril, or CNF. It is thin, flexible,
The researchers were able to use CNF as a substrate or base layer for electronic circuits in lab tests,
unlike a lot of the petroleum-based alternatives that manufacturers use to build the bases of modern computer chips.

#New laser for computer chips: International team of scientists constructs first germanium-tin semiconductor laser for silicon chips The transfer of data between multiple cores as well as between logic elements and memory cells is regarded as a bottleneck in the fast-developing computer technology.
Data transmission via light could be the answer to the call for a faster and more energy efficient data flow on computer chips as well as between different board components.
However in spite of intensive research a laser source that is compatible with the manufacturing of chips is not yet achievable according to the head of Semiconductor Nanoelectronics (PGI-9). The basis of chip manufacturing is silicon an element of main group IV of the periodic table.
